    • For water, the dipole moment is given by the H-O-H angle α and the O-H distance d, according to the relation |μ| = 2qHed cos α/2, where e is the elementary charge.

The equivalent atom-based charge for the 0 atom would be slightly higher than the sum of the two lone-pair charges because it would be placed nearer to the H atom.

    • m is the molar volume of a gas, and R is the universal gas constant. W is significantly smaller than the atomization energies, ionization energies, electron affinities, or cohesive energies (see Tables 3 and 4), so the difference between ΔH and ΔE can be neglected.

    • note
    • Ionization from the initial charge of -1 to ±0 requires less than the negligible amount of 0.05 MJ/mol for both Al and Mg (see refs 6 and 53). It is therefore sufficient to consider ionization from electroneutrality onward.
